[Feature Request] Expose the region or error used by MSAL

[bgavrilMS]

Part of AuthenticationResultMetadta, expose a string RegionOrDiscoveryError which is populated only if WithAzureRegion is used.

If region auto-detection failed, this metric should describe the reason (over and over again!)

{
AuthenticationMetadata.RegionDiscoveryOutcome -> [RegionOutcome, Exception, RegionUsed]
}

@bgavrilMS can this be prioritized for upcoming release?

[bgavrilMS]

We were thinking to wrap up msal 4.38 and not start new work. Note that MSAL exposes AuthentcationResultMetadata.TokenEndpoint, which will include the region. Is this not enough?

[jennyf19]

I think having the entire token endpoint is not straightforward for people who don't know what they are looking for. If this is not needed, close the issue. Can you also remove the 4.38 milestone, if it won't be in that release? Thanks.

@bgavrilMS The amount of work should be minimal, but the clarity to users should be beneficial. I propose we take this in the next release (maybe even do a quick small one).

[bgavrilMS]

Ok

[bgavrilMS]

I propose that we take this as we're getting more and more issues around auto-discovery.
